The bill amends the Michigan Penal Code to enhance penalties for crimes related to the adulteration and misuse of drugs, explosives, and harmful substances. It establishes felony charges for knowingly or recklessly adulterating drugs, with penalties that escalate based on the severity of harm caused, including potential life imprisonment for actions resulting in death. The bill also addresses the illegal use of harmful biological, chemical, and explosive substances, imposing severe penalties for violations that lead to property damage, personal injury, or death. New legal language is introduced to clarify definitions and penalties, particularly for using offensive substances to harm or intimidate others, and it reinforces the seriousness of these offenses by allowing life sentences without parole for individuals whose actions result in another person's death.

Furthermore, the bill amends laws concerning first-degree murder, poisoning, criminal sexual conduct, and terrorism. It mandates life imprisonment without the possibility of parole for individuals convicted of first-degree murder, including those who commit murder by poison or during the commission of certain felonies. The bill clarifies definitions of key terms and specifies conditions for convictions related to poisoning and harmful substances. It also emphasizes severe penalties for first-degree criminal sexual conduct involving minors, particularly for individuals aged 18 or older who have prior convictions. Additionally, it establishes life imprisonment without parole for those who cause death through terrorist acts. The amendments include various insertions and deletions to refine the legal language and framework surrounding these serious offenses.
